When trying to get rid of the cross-includes of <mach/id.h> from different drivers, so we can localize ASIC/CPU detection to the mach-ux500 folder, we run into the way the PRCMU handles base addresses and firmware detection. This patch updates the firmware version detection to pass the required information as platform data instead of relying on cpu_is_* macros. Now the PRCMU base address, the secondary TCDM area, the TCPM area and the IRQ are passed as resources instead of being grabbed from <mach/*> files. Incidentally this also removes part of the reliance on <mach/irqs.h>. Further it updates the firmware version detection, since the location of the firmware ID bytes in the designated memory are is now passed from the platform data instead. There is no reason not to include the nice split-off of a struct to hold the firmware information and a separate function to populate it. The patch actually rids the need to use the external db8500_prcmu_early_init call at all, but I'm keepin back that removal as I don't want the patch to be too big.
